Hello, I am a beginner in node red and would like to save the data from the dht22 sensor in mysql and display via chart. I have already tried a lot but unfortunately without success.
Don't ask me why, but now it works. I changed nothing! Went to my girl over the weekend, coming back, the node was registred. Maybe a jammer went away?
@Mizar03 sorry for the late response. getStream() only works for firmware transfers. I'd suggest getString(), this should also work for all types of payloads, as they are normaly ASCII and not binary data.
Hi all,
Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May.
Hope this helps.
